  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: carl9170: bound memcpy length in cmd callback to prevent OOB read\n\nWhen the firmware sends a command response with a length mismatch,\ncarl9170_cmd_callback() logs the mismatch and calls carl9170_restart()\nbut then falls through to memcpy(ar-\u003ereadbuf, buffer + 4, len - 4).\nSince len comes from the firmware and can exceed ar-\u003ereadlen, this\ncopies more data than the readbuf was allocated for.\n\nBound the memcpy to min(len - 4, ar-\u003ereadlen) so that the response\nis still completed -- avoiding repeated restarts from queued garbage --\nwhile preventing an overread past the response buffer.",
